| Constructor and Description |

TimingTraceListener() |
| Modifier and Type | Method and Description |
|---|---|
void |
close()
Called at end.
|
void |
endCurrentItem(Item item)
Called after a node of the source tree got processed
|
void |
enter(InstructionInfo instruction,
XPathContext context)
Called when an instruction in the stylesheet gets processed
|
PreparedStylesheet |
getStyleSheet()
Prepare Stylesheet to render the analyzed XML data out.
|
void |
leave(InstructionInfo instruction)
Called after an instruction of the stylesheet got processed
|
void |
open(Controller controller)
Called at start
|
void |
setOutputDestination(PrintStream stream)
Set the PrintStream to which the output will be written.
|
void |
startCurrentItem(Item item)
Called when an item becomes current
|
public void setOutputDestination(PrintStream stream)
setOutputDestination in interface TraceListenerstream - the PrintStream to be used for output. By default, the output is written
to System.err.XPathExceptionXMLStreamExceptionpublic void open(Controller controller)
open in interface TraceListenercontroller - identifies the transformation controller, and provides the listener with
access to context and configuration informationpublic void close()
close in interface TraceListenerpublic void enter(InstructionInfo instruction, XPathContext context)
enter in interface TraceListenerinstruction - gives information about the instruction being
executed, and about the context in which it is executed. This object is mutable,
so if information from the InstructionInfo is to be retained, it must be copied.public void leave(InstructionInfo instruction)
leave in interface TraceListenerinstruction - gives the same information that was supplied to the
enter method, though it is not necessarily the same object. Note that the
line number of the instruction is that of the start tag in the source stylesheet,
not the line number of the end tag.public void startCurrentItem(Item item)
startCurrentItem in interface TraceListeneritem - the new current item. Item objects are not mutable; it is safe to retain
a reference to the Item for later use.public void endCurrentItem(Item item)
endCurrentItem in interface TraceListeneritem - the item that was current, whose processing is now complete. This will represent
the same underlying item as the corresponding startCurrentItem() call, though it will
not necessarily be the same actual object.public PreparedStylesheet getStyleSheet() throws TransformerConfigurationException
